=head1 SYNOPSIS

This module reads Win32 shortcuts (*.lnk files) to obtain the meta data in them.

Its goal is to be able to resolve the path they point to (along with other data),
from any platform/OS, without the need for depencencies.

Its use is very simple:

    use Parse::Lnk;

    my $data = Parse::Lnk->from($filename);

    # $data is now a hashref if the file was parsed successfully.
    # undef if not.

    ##########
    # Or ... #
    ##########

    use Parse::Lnk qw(parse_lnk);

    my $data = parse_lnk $filename;

    # $data is now a hashref if the file was parsed successfully.
    # undef if not.

    ##########
    # Or ... #
    ##########

    use Parse::Lnk qw(resolve_lnk);

    my $path = resolve_lnk $filename;

    # $path is now a string with the path the lnk file points to.
    # undef if the lnk file was not parsed successfully.

    ###############################################################
    # Or, if you want a little more information/control on errors #
    ###############################################################

    use Parse::Lnk;

    my $lnk = Parse::Lnk->new;

    $lnk->parse($filename) or die $lnk->{error};

    # Or:

    $lnk->parse($filename);

    if ($lnk->{error}) {
        # ... do your own error handling;
    }




=head1 EXPORT

Nothing is exported by default. You can explicitly import this functions:

=head2 parse_lnk($filename)

This will return a Parse::Lnk instance, which is a hashref. The keys in that
hashref depend on the data that was parsed from the .lnk file.

It will return C on error.

    use Parse::Lnk qw(parse_lnk);

    my $lnk = parse_lnk $filename;

    if ($lnk) {
        print "$filename points to path $lnk->{base_path}\n";

        my $create_date = localtime $lnk->{create_time};
        print "$filename was created on $create_date";
    } else {
        print "Could not parse $filename";
    }

=head2 resolve_lnk($filename)

This will return the path the .lnk file is pointing to.

It will return C on error.

    use Parse::Lnk qw(resolve_lnk);

    my $path = resolve_lnk $filename;

    if ($path) {
        print "$filename points to path $path";
    } else {
        print "Could not parse $filename";
    }


=head1 METHODS

You can create a C instance and call a few methods on it. This
may give you more control/information when something goes wrong while parsing
the file.

=head2 new

This creates a new instance. You can pass the C value as argument,
or you can set/change it later.

    use Parse::Lnk;

    my $lnk = Parse::Lnk->new(filename => $filename);

    # or

    my $lnk = Parse::Lnk->new;
    $lnk->{filename} = $filename;

=head2 parse

This method will parse the current C in the instance. You can change
the value of C and parse again at any point.

    use Parse::Lnk;

    my $lnk = Parse::Lnk->new(filename => $filename);

    $lnk->parse;

    if ($lnk->{error}) {
        # handle the error
    } else {
        print "$filename points to $lnk->{base_path}";
    }

    for my $other_filename (@filenames) {
        $lnk->{filename} = $other_filename;
        $lnk->parse;

        if ($lnk->{error}) {
            # handle the error
            next;
        }

        print "$other_filename points to $lnk->{base_path}";
    }

=head2 from

It will return a C instance, or undef on error. This method was
written with plain package name calling in mind:

    use Parse::Lnk;

    my $lnk = Parse::Lnk->from($filename);

    if ($lnk) {
        print "$filename points to path $lnk->{base_path}\n";

        my $create_date = localtime $lnk->{create_time};
        print "$filename was created on $create_date";
    } else {
        print "Could not parse $filename";
    }

=head1 BUGS

I'm sure there are many. I haven't found bugs with the lnk files I've tested
it. If you find a bug or you have a problem reading a shortcut/lnk file,
please don't hesitate to report it and don't forget to include the file in
question. If you are on Windows, you will have to zip the file in a way that
is the lnk file the one being zipped and not the actual directory/file it
is pointing to. I promise to look at any report and work on a solution as
fast as I can.

Please report any bugs or feature requests to C, or through
the web interface at L.  I will be notified, and then you'll
automatically be notified of progress on your bug as I make changes.
